A technique and some preliminary results of a study of the damage state of a long fiber reinforced thermoplastic composite are presented, emphasizing the difficulty encountered when the matrix material contributes significant viscoelastic effects to the material response. The type and origin of these effects are reviewed, as is the theory that has been developed allowing for removal of the superimposed viscoelastic effects. It is demonstrated that the complicating effect of the superimposed viscoelasticity can be successfully removed, thereby providing a less confusing presentation of the data and offering the potential for greatly simplified design and analysis.
